Overview



We fabricate, manufacture, rent, and sell natural gas compressors and related
equipment. Our primary focus is on the rental of natural gas compressors. Our
rental contracts typically provide for initial terms of six to 24 months, with
our larger horsepower units having contract terms of up to 60 months. After the
initial term of our rental contracts, many of our customers have continued to
rent our compressors on a month-to-month basis. Rental amounts are billed
monthly in advance and include maintenance of our rented compressors. As of
March 31, 2022, we had 1,276 natural gas compressors totaling 306,834 horsepower
rented to 79 customers compared to 1,265 natural gas compressors totaling
287,914 horsepower rented to 80 customers at March 31, 2021.

We also fabricate natural gas compressors for sale to our customers, designing
compressors to meet unique specifications dictated by well pressures, production
characteristics, and particular applications for which compression is sought.
Fabrication of compressors involves our purchase of engines, compressors,
coolers, and other components, and our assembling of these components on skids
for delivery to customer locations. The major components of our compressor
packages are acquired through periodic purchase orders placed with third-party
suppliers on an "as needed" basis, which presently require lead times between
three to six months with delivery dates scheduled to coincide with our estimated
production schedules. Although we do not have formal continuing supply contracts
with any major supplier, we believe we have adequate alternative sources
available. Recent inflationary pressures have created price increases in both
major and minor components for our compressors as well as longer than normal
lead times for such components. To date, we have been able to increase our
rental rates and sales prices proportionally; however, if cost increases
continue and we are no longer able to increase our rental rates and sales prices
such an event could have a material adverse effect on the results of our
operations and financial condition.

We also manufacture a proprietary line of compressor frames, cylinders and
parts, known as our CiP (Cylinder-in-Plane) product line. We use finished CiP
component products in the fabrication of compressor units for sale or rental by
us or sell the finished component products to other compressor fabricators. We
also design, fabricate, sell, install, and service flare stacks and related
ignition and control devices for onshore and offshore incineration of gas
compounds such as hydrogen sulfide, carbon dioxide, natural gas and liquefied
petroleum gases. To provide customer support for our compressor and flare sales
businesses, we stock varying levels of replacement parts at our Midland, Texas
facility and at field service locations. We also provide an exchange and rebuild
program for screw compressors and maintain an inventory of new and used
compressors to facilitate this business.

We provide service and maintenance to our customers under written maintenance contracts or on an as-required basis in the absence of a service contract. Maintenance agreements typically have terms of six months to one year and require payment of a monthly fee.

--------------------------------------------------------------------------------


The oil and natural gas equipment rental and services industry is cyclical in
nature. The most critical factor in assessing the outlook for the industry is
the worldwide supply and demand for oil and natural gas and the corresponding
changes in commodity prices. As demand and prices increase, oil and natural gas
producers typically increase their capital expenditures for drilling,
development and production activities, although recent equity capital
constraints and demands from institutional investors to keep spending within
operating cash flow have meaningfully restrained capital expenditure budgets of
domestic exploration and production companies. Generally, increased capital
expenditures ultimately result in greater revenues and profits for service and
equipment companies.

In general, we expect our overall business activity and revenues to track the
level of activity in the oil and natural gas industry, with changes in crude oil
and condensate production and consumption levels and prices affecting our
business more than changes in domestic natural gas production and consumption
levels and prices. In recent years we have increased our rentals and sales in
unconventional oil shale plays, which are more dependent on crude oil prices.
With this shift towards oil production, the demand for overall compression
services and products is driven by two general factors: an increased focus by
producers on artificial lift applications, e.g., production enhancement with
compression assisted gas lift; and declining reservoir pressure in maturing
natural gas producing fields, especially unconventional production. These types
of applications have historically been serviced by wellhead size compressors,
and continue to be, but there has also been an economic move by our customers
towards centralized drilling and production facilities, which have increased the
market need for larger horsepower compressor packages. We recognized this need
in recent years and have been shifting our cash and fabrication resources
towards designing, fabricating and renting gas compressor packages that range
from 400 horsepower up to 1,500 horsepower. While this is a response to market
conditions and trends, it also provides us with the opportunity to compete as a
full-line compression provider.

Industry Update



We typically experience a decline in demand during periods of low crude oil and
natural gas prices. During the first quarter of 2020, we saw a substantial
decline in the prices for oil and natural gas. Commodity prices stabilized
during 2021 with a sharp increase through the first three months of 2022.
Historically, activity levels of exploration and production companies have been
dependent on commodity prices. However, recent capital market focus on cash
returns from exploration and production companies has restricted capital
spending below levels that have historically been observed during higher
commodity price environments. Generally, though, we feel that production
activities (in which we are involved) will fare better than drilling activity.
This is reflected in both the stability of our rental revenues, which is driven
by production activities, and the volatility of our compressor sales, which
tends to fluctuate with capital allocations. As such, we still expect compressor
sales to be low for the remainder of 2022, as exploration and production
companies have elected to rent compression units rather than allocating capital
dollars to purchase new compression.

Results of Operations

Three months ended March 31, 2022, compared to the three months ended March 31, 2021.

The table below shows our revenues and percentage of total revenues of each of our product lines for the three months ended March 31, 2022 and 2021.



                                                               Three months ended March 31,
                                                                2022                                  2021
                                                                      (in thousands)
Rental                                                  $       17,129            84.2  %          $    15,341            83.4  %
Sales                                                            2,893            14.2  %                2,711            14.7  %
Service and Maintenance                                            314             1.5  %                  345             1.9  %
Total                                                   $       20,336                             $    18,397




Total revenue increased 10.5% to $20.3 million for the three months ended March
31, 2022 compared to $18.4 million for the three months ended March 31, 2021.
This increase was primarily a result of higher rental revenue (11.7% increase)
during 2022 as well as higher sales revenue (7% increase).

                                       15
--------------------------------------------------------------------------------

Rental revenue increased to $17.1 million for the three months ended March 31,
2022 compared to $15.3 million for the same period in 2021. This increase during
the first quarter of 2022 was attributable to an increase in high horsepower
compression rentals as these units carry a higher revenue rate than our lower
horsepower units.

As of March 31, 2022, we had 2,033 compressor packages in our fleet, down from
2,238 units at March 31, 2021 due to the retirement of units during the fourth
quarter of 2021. The Company's total unit horsepower decreased to 421,422
horsepower at March 31, 2022 compared to 441,911 horsepower at March 31, 2021,
due to the aforementioned unit retirements in the fourth quarter of 2021
partially offset by the addition to the Company's fleet of 27 high horsepower
compressors with 10,900 horsepower over the past 12 months. As of March 31,
2022, we had 1,276 natural gas compressors with a total of 306,834 horsepower
rented to 79 customers, compared to 1,265 natural gas compressors with a total
of 287,914 horsepower rented to 80 customers as of March 31, 2021. As a result,
our total rented horsepower as of March 31, 2022 increased by 6.6% over the last
twelve months. Our rental fleet had unit utilization as of March 31, 2022, and
2021, respectively, of 62.8% and 56.5%, and our horsepower utilization for the
same period ends increased to 72.8% from 65.2%. Our total rented horsepower
increased by 6.6% contrasted against a 0.9% increase in total rented units. This
illustrates the growing demand for our high horsepower units while the demand
for our smaller and medium horsepower units has not recovered in line with
recent commodity price increases.

Sales revenue increased to $2.9 million for the three months ended March 31,
2022 compared to $2.7 million for the three months ended March 31, 2021. This
increase is mostly attributable to increased compressor sales during the first
quarter of 2022 compared to the same period in 2021. Sales are subject to
fluctuations in timing of industry activity related to our customers' capital
projects and, as such, can vary substantially between periods.

Cost of rentals increased to $9.2 million during the three months ended March
31, 2022 compared to $7.2 million during the three months ended March 31, 2021.
While rental revenues increased 11.7%, this 29.0% increase in costs of rentals
is primarily due to inflationary pressures on labor and parts as well as a
significant increase in repair and maintenance work on our rental fleet. While
repair and maintenance expenses are customary in our business, the timing of
such expenses can fluctuate between periods resulting in periods with larger
than normal expenses.

Cost of sales decreased 24.0% to $2.0 million during the three months ended
March 31, 2022 compared to $2.6 million during the three months ended March 31,
2021. This decrease was primarily due to a reduction in unabsorbed costs during
the period.

Selling, general, and administrative ("SG&A") expenses decreased 5.5% to $2.5
million for the three months ended March 31, 2022 compared $2.6 million during
the same period in 2021. This decrease in SG&A expenses was primarily
attributable to a decrease in stock compensation expense and a decrease in
non-cash charges related to our deferred compensation program.

Depreciation and amortization expense decreased to $6.1 million for the three
months ended March 31, 2022 compared to $6.3 million for the three months ended
March 31, 2021. This was the result of a reduction in our rental fleet due to
unit retirements in the fourth quarter of 2021.

We recorded an income tax benefit of approximately $11,000 for the three months
ended March 31, 2022 compared to an income tax expense of $(125,000) for the
three months ended March 31, 2021. For interim periods, our income tax benefit
(expense) is computed based upon our estimated annual effective tax rate and any
discrete items that impact the interim periods. Our estimated annual effective
tax rate differs from the U.S. federal statutory rate of 21%.

Non-GAAP Financial Measures

Our definition and use of Adjusted EBITDA



"Adjusted EBITDA" is a non-GAAP financial measure that we define as earnings
(net (loss) income) before interest, taxes, depreciation and amortization, as
well as non-cash stock compensation, impairment of goodwill, an increase in
inventory allowance and inventory write-offs, and retirement of rental
equipment. This term, as used and defined by us, may not be comparable to
similarly titled measures employed by other companies and is not a measure of
performance calculated in accordance with GAAP. Adjusted EBITDA should not be
considered in isolation or as a substitute for operating income, net income or
loss, cash flows provided by operating, investing and financing activities, or
other income or cash flow statement data prepared in accordance with
GAAP. However, management believes Adjusted EBITDA is useful to an investor in
evaluating our operating performance because:
                                       16
--------------------------------------------------------------------------------

•it is widely used by investors in the energy industry to measure a company's
operating performance without regard to items excluded from the calculation of
Adjusted EBITDA, which can vary substantially from company to company depending
upon accounting methods and book value of assets, capital structure and the
method by which assets were acquired, among other factors;

•it helps investors to more meaningfully evaluate and compare the results of our
operations from period to period by removing the impact of our capital structure
and asset base from our operating structure; and

•it is used by our management for various purposes, including as a measure of operating performance, in presentations to our Board of Directors, and as a basis for strategic planning and forecasting.

Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our results as reported under generally accepted accounting principles. Some of these limitations are:

•Adjusted EBITDA does not reflect our cash expenditures, future requirements for capital expenditures, or contractual commitments;

•Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;

•Adjusted EBITDA does not reflect the cash requirements necessary to service interest or principal payments on our debts; and

•although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect any capital expenditures for such replacements.



There are other material limitations to using Adjusted EBITDA as a measure of
performance, including the inability to analyze the impact of certain recurring
items that materially affect our net income or loss, and the lack of
comparability of results of operations of different companies. Please read the
table below under "Reconciliation" to see how Adjusted EBITDA reconciles to our
net (loss) income, the most directly comparable GAAP financial measure.

Reconciliation

The following table reconciles our net (loss) income, the most directly comparable GAAP financial measure, to Adjusted EBITDA:


                                             Three months ended March 31,

                                                    (in thousands)
Net income (loss)                     $          337                    $  (394)

Non-cash stock compensation expense              423                        474

Adjusted EBITDA                       $        6,834                    $ 6,503

For the three months ended March 31, 2022, Adjusted EBITDA increased $0.3 million (5.1%) due primarily to a $1.9 million increase in total revenues and a $0.6 million reduction in costs of sales partially offset by a $2.1 million increase in costs of rentals.

              Total working capital            $  40,175      $      44,825



For the three months ended March 31, 2022, we invested $8.2 million in rental
and property and other equipment. During the three months ended March 31, 2022,
we added $8.1 million in new equipment to our rental fleet and $0.1 million
mostly in vehicles as well as various other machinery and equipment. Our
investment in rental equipment, property and other equipment also includes any
changes to work-in-process related to our rental fleet jobs at the beginning of
the period compared to the end of the period. Our rental work-in-process
increased by $1.6 million during the three months ended March 31, 2022. We
financed our investment in rental equipment, property and other equipment with
cash flow from operations and cash on hand. We anticipate that our cash flows
from operations as well as our borrowing capacity under our New Credit Agreement
will provide ample liquidity for our planned capital expenditures during the
remainder of 2022 and beyond.

Cash flows



At March 31, 2022, we had cash and cash equivalents of $16.4 million compared to
$22.9 million at December 31, 2021. Our cash flows from operating activities of
$5.0 million were offset by capital expenditures of $8.2 million during the
three months ended March 31, 2022. We had working capital of $40.2 million at
March 31, 2022 compared to $44.8 million at December 31, 2021. We generated cash
flows from operating activities of $5.0 million during the first three months of
2022 compared to cash flows provided by operating activities of $7.4 million for
the first three months of 2021. The decline in cash flows from operating
activities was primarily driven by higher costs of rentals during the first
three months of 2022. These increases were partially offset by slightly higher
sales margins.

Strategy

For the remainder of 2022, our overall plan is to continue monitoring and
holding expenses in line with the anticipated level of activity, fabricate
rental fleet equipment only in direct response to market requirements, emphasize
marketing of our idle gas compressor units and limit bank borrowing in line with
market conditions. For the remainder of 2022, our forecasted capital
expenditures are not anticipated to exceed our internally generated cash flows
and our cash on hand. Any required capital will be for contracted,
premium-priced additions to our compressor rental fleet and/or required service
vehicles. We believe that cash flows from operations and our current cash
position will be sufficient to satisfy our capital and liquidity requirements
for the foreseeable future.
